Clarifications:
Essential Understandings
Concrete:
- Identify the shorter or longer unit of measurement (e.g., inches are smaller than feet).
- Understand that the appropriate unit of measure is the one that will require fewer units to measure the object (Ex: Select inches to measure the length of a pencil. Select feet to measure the length of the classroom).
- Identify which tool is appropriate to measure an object (Ex: a ruler for the length of a pencil, a yardstick for the length of a classroom).
- Match the visual representation of the object to the appropriate tool for measuring its length (Ex: match the ruler to the pencil, match the yardstick to the picture of the classroom).
- Understand the following concepts and vocabulary of inches, feet, ruler, yardstick, measurement, length, tool, and unit.

Cluster:
Measure and estimate lengths in standard units. (Major Cluster) :
Clusters should not be sorted from Major to Supporting and then taught in that order. To do so would strip the coherence of the mathematical ideas and miss the opportunity to enhance the major work of the grade with the supporting clusters.
